High‑efficiency two‑stage technology for powder dispersion, mixing, and transfer The SII‑AL‑M15 Powder Rehydration System is a mobile, high‑efficiency, two‑stage in‑line mixing unit designed for rapid dissolution and homogeneous mixing of powders into liquids for dairy, beverage, and food applications. This all‑in‑one solution integrates a high‑shear mixer and a centrifugal pump into a single compact unit, ensuring complete solid dissolution and efficient product transfer without the need for auxiliary equipment. The two‑stage configuration enables automatic powder induction by vacuum, uniform dispersion into the liquid phase to prevent agglomeration, and controlled pumping of the final mixture back to the tank. The first stage consists of a rotor‑stator mixing system that provides intensive shear for effective powder wetting and dispersion. The second stage uses a pump impeller to apply final shear and deliver the homogeneous mixture under pressure. A hygienic C‑ball valve isolates the injection system and promotes negative pressure at the hopper outlet, optimizing powder feeding and dissolution. The recirculating liquid flow continuously generates and maintains vacuum at the ejector. Designed to operate within a batch tank recirculation loop, the SII‑AL‑M15 ensures consistent mixing performance and process repeatability. For large tanks, the use of a rotary jet mixer is recommended to further improve overall mixing efficiency. After the mixing phase, the unit can operate as a discharge pump or CIP recirculation pump, simplifying cleaning procedures and reducing maintenance time when integrated with rotary jet mixing systems. The SII‑AL‑M15 is particularly suitable for processing challenging ingredients such as thickeners, stabilizers, and emulsifiers, and for milk recombination applications with total solids concentrations exceeding 50%, meeting hygienic processing requirements for precision and efficiency.
